BYRON BOOTH, OF EAST LIVERPOOL, OHIO.

DECORATING POTTERY-WARE.

SPECIFICATION forming part of Letters Patent No. 452,254, dated May 12, 1891.

Application filed December 9, 1890.

To all whom it may concern: 7

Be it known that I, BYRON BOOTH, of East Liverpool, in the county of Oolumbiana and State of Ohio, have invented certain new and useful Improvements in Processes of Decorating Pottery-Ware and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it.

My invention relates to an improvement in processes of decorating pottery-ware; and it consists in the manner of applying coloringmatter to the article being manufactured, as

hereinafter fully described, and pointed out in the claims.

The object of my invention is to decorate the clay before it is formed into an article of any kind, instead of applying the colors to the glazed article after it has been finished, and thus producing not only more beautiful colors and tints, but making the colors practically form a part of the article itself before the glaze is applied. I takea bat of clay and after forming it the colors in a thick liquid state are applied to its surface in large or small spots until the surface is partially covered. The hat of clay is then placedupon a board and given a rapid circular motion at the same time that the hands are applied to the surface of the clay so as to cause the colors to flow together and form shapes of different kinds. The clay is then placed in a heated room, in which it remains until the moisture on its surface has evaporated, and then it is put in a mold and made into a vessel or article of any desired kind. This vessel is then baked and glazed in the usual manner. The color or decoration is applied to the clay before it is placed in the molds, and hence the color becomes incorporated into the surface of the clay, making the colors and tints more brilliant and delicate and greatly cheapening the process of decorating glazed ware.

I-Ieretofore the process of printing and decorating white ware has been as follows: After the article of whatever kind has been made it is placed in a kiln and fired, and the article is then called biscuit-Ware. The biscuits are dipped in a glaze and fired a second time, when the colors are applied to the glaze, and it is then fired a third time in a small kiln to a moderate heat just sufficient to bake the colors on the glaze. By my process much of this labor is saved and the glaze is baked over the colors instead of the colors being baked upon the glaze.

Having thus described my'process, I claim-- 1. A process of decorating pottery-ware, consisting of the following successive steps: form-. ing a bat, applying a number of liquid colors thereto in spots, causing the colors to flow together by agitating them, forming the bat into the desired article, and then baking it, substantially as specified.

2. The process of decorating pottery-ware,

, consisting in applying color to the surface of the bat of clay, then subjecting the bat to a rapid circular motion and causing the colors and tints to flow together by applying slight pressure to the clay while it is revolving, then molding the bat into the desired article, and then baking the color into the article after it is formed and before the glaze is applied, substantially as set forth.

3. A process of decorating pottery-ware, consisting of the following successive steps: forming a bat, applying a number of liquid coloring-matters thereto, causing the colors to flow together by a movement of the bat, evaporating the moisture on the surface'of the bat, forming the bat into the desired article, and then baking it, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
